Maryland has identified its first case of a Brazil-based variant of the coronavirus, according to Gov. Larry Hogan.

The case involves a D.C.-region resident over age 65 who died after returning from international travel, according to a press release issued by Hogan on Wednesday. State health officials are working to identify and quarantine individuals who came in contact with the resident.

The case marks the third variant of the coronavirus circulating in the state. Three cases of the South Africa strain have been reported in the state — two in Montgomery County, and one in Baltimore. The state also reported the U.K. variant in two Anne Arundel County residents in January, and Prince George’s County health director Ernest Carter told DCist last week there has been one case of the U.K. variant identified in the county. The U.K. and South Africa variants have also been reported in D.C. and the Northern Virginia region. 

Like the U.K. and South Africa variants, experts believe the Brazilian variant to be more transmissible than other strains of the coronavirus, but it hasn’t shown to be more lethal. However, the mutation has ravaged Brazil where it first originated, prompting another overwhelming surge of cases after the country largely believed it was moving toward herd immunity. In some cases, the variant reinfected residents who had already contracted and recovered from the virus.

The Pfizer and Moderna vaccines have shown to only be slightly less effective against the three variants circulating in the region, but the reinfection data from the Brazilian variant could indicate a mutation that would possibly evade vaccine efficacy, according to experts.
